For this pur surface of the sameand in'parallel relation pose the'same principle may be largely car asindicated in Figure3. o I i ried out, and the price would be consistentThe weight of'the body is carried upon a plurality of coil'springs 8 and8A, and with i with the market in this line.

Member9 has integral ears 11 which engage similar ears 12 of portion 1by means of rivets 13, and the said rivet stationaryiwith ear 12, andpermitting oscillating movement of member 9 by virtue of elongated slot14 in the ears 12, while member 10 has integral cars 15 which engagesimilar cars 16 of portion 1 by means of rivet 17, and this rivetstationary, with car 15, and by virtue. of

elongated slot 18 oscillating movement is effected relative to portion 1and member 10. Coil springs 8 and'SA are retained in their respectiveposition in relation to portion 1 and members Qand 10 by means'of bosses19 of portion 1', and'similar bosses 20 of membersaand 10. v

The action ofmembers Sand 10 is limited by'means of lugs 21 of portion1, and similar lugs 22 of th'e'said members,'and with reference toFigures 3, (land 7 it is clearly seen that each of the lugs 21 and 22isprovided with a laterally-extending opening through which passes oneend of one of the respective coilisprings oftheldevice.

By referring to Figures' l and 5 it is seen that the entire underneathsurface of members9and 10 has diagonally disposed check ered'surface23,the purpose of-which is understood. I v v lVith reference to Figures8 and 9,- it will be understood that the device may be very effectively:used in l laying asphalt pavingby substituting member' 9 with member 9B,the

latterj having similar elements to member 9 as follows "Coil springs 83,bosses 20B, lug 22B, in-

tegralears 11B, andcheckered surface 23B.

Itis also noted that member 93 is of greater width'and length thanmember 9, and also has tapering flange 2%1 formed as a part of the same,and rendering the device readily ap plicabl e' for this work.

The aforesaid plate member andthe lower members?) andlO ofthe device maybe composed of pressed steel or of aluminum cast metal, the latter beingpreferable owing to low cost of production, and also effecting a greatsaving of weight in'these elements without sacr1fic1ng strength anddurability.

My. invention is very substantially constructed, and with' ordinary careit will endure for an indefinite period of time, and while I have hereinset forth one precise embo'dnnent'of the invent on, the same is neverofthe changes so indicated during any probable further development of thedevice for the market, a departure from the general principle asdisclosed would of course be consistently avoided.

Still another advantage of my invention, and one of no less importancethan those heretofore related is-that due to the: extreme simple methodof design and construction employed, it may be manufactured at a lowcost andlthereby effecting a correspondingly low selling price addingmuch to the merit of the device-'particularly from a commer' cialviewpoint.
